UNLABELLED We present TreeDom, a web tool for graphically analysing the evolutionary history of domains in multi-domain proteins. Individual domains on the same protein chain may have distinct evolutionary histories, which is important to grasp in order to understand protein function. For instance, it may be important to know whether a domain was duplicated recently or long ago, to know the ori...

Building on recent work by Rosenzweig (1999), this paper re-examines the effect of AFDC benefits on early non-marital childbearing. Unlike most previous work in this area, Rosenzweig finds a statistically significant and quantitatively large positive effect of AFDC benefits. Using data from the Panel Study of Income Dynamics, we replicate Rosenzweig’s analysis and explore the reasons his findin...

BACKGROUND Explicit comparisons based on the semantic similarity of Gene Ontology terms provide a quantitative way to measure the functional similarity between gene products and are widely applied in large-scale genomic research via integration with other models. Previously, we presented an edge-based method, Relative Specificity Similarity (RSS), which takes the global position of relevant ter...

The present paper deals with the study of wetland plants in “Kapla beel” area Barpeta district Assam (India). A total 107 angiospermic plant species belonging to 80 genera, 37 families, and 21 orders are taken into consideration. Treatment taxa according APG-IV system classification reveals existence 4 ANA-grade species. clade Magnoliids has been recorded only a single Commelinids is 50 under 1...

PURPOSE We have been engaged in an ongoing study to screen candidate genes for mutations in small families with various forms of autosomal recessive retinal dystrophy. Here we report the screening of a cohort of 14 families from Sardinia for mutations in the genes encoding the alpha- and beta-subunits of cGMP-phosphodiesterase and RPE65 (PDE6A, PDE6B, and RPE65). METHODS Haplotype analysis wa...

BACKGROUND Development of sensitive sequence search procedures for the detection of distant relationships between proteins at superfamily/fold level is still a big challenge. The intermediate sequence search approach is the most frequently employed manner of identifying remote homologues effectively. In this study, examination of serine proteases of prolyl oligopeptidase, rhomboid and subtilisi...

the present survey deals with the floristic study of dalab woodlands, located in manesht and ghelarang protected area, western iran. it covers an area of 4335 ha. in total, 224 vascular plant species belonging to 46 families and 156 genera were identified. the largest families are asteraceae (29 species), fabaceae (23 species), poaceae (22 species), and apiaceae (18 species). astragalus (13 spe...

in the present study, we reported the results of the monitoring and investigations of the ichthyofauna of the beshar river, one of the tributaries of the tigris−euphrates basin in kohkiluyeh and boyer-ahmad province, southwest of iran. the results showed that during a period from 2010 to 2011, a total of 13 fish species belonging to 4 families and 3 orders were recorded in the beshar river. the...

during 1995-1997, a faunistic survey was carried out on spider mites and their predacious mites in urmieh region, iran. a total of 15 species belonging to 7 families and 13 genera were collected and identified, of which one genus and species is a new record for iran (marked by two asterisks), and 6 species are new records for west azerbaijan province (marked one asterisks).
